Last year I was on flight from IAH-PHX on 10/22 (should be) on US Air 180 (B735). The official forecast called for a "twisted" jetstream over NM and TX border. Pilot stated that there would be some bumps before landing. We met the first round (SW-NE bound) jetstream near El Paso, TX. Flight level was about 33000 feet. The plane moved horizontally with ocassions of drops. Then the pilot lowered the altitude to 24000 feet (checked with flightaware.com). Lasted about 15 minutes. There was no cloud, but looked "hazy" outside from the window. When air stabilized, the pilot climbed back to FL330. Within 30 minutes, after crossing into NM, we hit the south bound running jetstream. This time, again, clear air with haze. I looked out to the windows and the plane actually moves L/R on the yaw axis, as well as feeling up and down. Again, down to some FL240. Lasted about 20 minutes. Over PHX there were some moderate turbulence. I changed plane at PHX to LAX, and looked at the smoke from the mountains. Before touch down, there were some turbulence again.
